BOTTLE-CAP.

Specification of Letters Patent.

Patented Dec. 10, 1918.

Application filed November 8, 1917. Serial No. 200,191.

T 0 all whom it may concern:

Be it known that I, ALFRED L. BERNARDIN, a citizen of the United States, and a resident of Evansville, in the county of Vanderberg and State of Indiana, have invented a new and useful Improvement in Bottle-Caps, of which the following is a specification.

My present invention relates generally to bottle caps and more particular to bottle caps for catsup bottles and the ike of the type described and claimed in my Patent No. 1,244,413, granted October 23, 1917.

The primary object of my present improvement is the rovision of a cap construction which wil avoid the necessity of screwing the ca upon the bottle and which will thus avoi a great waste of time in opening and closing a bottle durin the gradua using of the contents thereo and also avoid the initial manual screwing of the cap prior to the ap lication of power thereto for compressing t e sealing member in the first instance.

In the accompanying drawing illustrating my present invention Figure 1 is a perspective view of a portion of a bottle neck provided with my im proved cap sealed thereon,

Fig. 2 1s a vertical sectional view illustrating the cap in inoperative connection with the bottle neck before sealing,

Fi 3 is a similar view with the parts in sealed position,

Fig. 4 is a side view of the bottle neck as I propose to construct the same,

Fig. 5 is a horizontal sectional view taken substantially on the line 55 of Fig. 3,

Fig. 6 is a side view of one portion of a ca of slightly modified form, and

ig. 7 is a vertical sectional view through the modified cap upon a bottle neck.

In the constructlon proposed by m Ecsent invention the bottle cap has-a oc ng means in connection with a bottle engage able by rectilinear movement of the ca with respect to the bottle to engage an clamp a rtion of the latter, and as 1n 1ny patent a ove referred to, is also provided with sealing means for engagement with a separate portion of the bottle in the'first instance, so that after the bottle has been filled by the manufacturer it is simply necessary to place the open end of the cap upon the mouth of the bottle and the pressure member for compressing the interna disk of the cap serves in the present insealing stance to force the cap onto the bottle neck to move that part of the locking means carried thereby beyond that part of the lock- 1ng means carried by the bottle and shift the sealing means into the operative posit1on for engagement with an annular shoulder of the bottle provided for the reception thereof.

My present invention thus distinguishes from my patent,above referred to by virtue,

of the elimination of the necessity of rotating the cap, which must, of course, be done by hand so as to engage the ca with the bottle in the first instance an makes it ossible to perform both of these 0 erations y the com ressing member when t e bottle is initial] lled and also enables more ready and quic engagement of the cap with the bottle and disengagement of the cap from the bottle in the after use of the bottle during the gradual consumption of the contents thereof.

Referring specifically to the figures of the drawing before described my present invention provides a bottle neck 10 having ad'acent its open end or mouth an annular rounded enlargement 11 and provided be low the said enlargement with an annular shoulder 12', the latter providing a lower square face and being farthest removed from the mouth 13 of the bottle neck upon which in the initial sealing of the bottle the usual cork or sealing disk 14 of other material is disposed.

To cooperate with the bottle neck so' formed the ca 15, which is closed at one end at 16 and is 0 en at its opposite end, is provided at a point intermediate its ends with an annular series of depressed portions or indentations 17, its diameter being so related to the diameter of the bottle neck that these indentations may be pressed downwardly over the enlargement 11 of the bot tle neck by virtue of resiliency of the cap and the indentations 17 so as to lock the cap upon the bottle neck. -This construction provides for quick and convenient at taehment and detachment of the cap by the consumer during the gradual consumption of the contents of the bottle, and inasmuch as the indentations 17 of the cap in a single annular series move ast the enlargement 11, the said construction provides also for the use of a sealing means by further compressing the cap 15 to force the same longitudinally of the bottle neck so as to thus compress the sealing disk 14 against the mouth 13 of the bottle neck and between the I same and the closed end 16 of the cap.

Asabove stated the sealing disk maiv be constructed of various materials suitab e in the formation of an air and liquid-tight joint and in compressing this disk a suite le pressure member 18 as seen in Fig. 3 is employed within a suitable machine for this purpose, the action of which forces the catp upon the bottle neck to provide or its sealing inde endent of the actionof the indentations 1 in connection with the bottle neck enlargement 11, which latter would be insufficient for the purpose of supporting the parts in sealed position.

As in my patent above referred to the 1nner edge of the cap 15 around its open end has an extension metal band 19 so as to permit of ready flanging or rolling of the inner free edge thereof beneath the lower edge of the bottle neck shoulder 12 as seen clearly in Fig. 3, the opposite edge of this extension band being connected to the said lower. inner edge of the cap around its'open end by means of a seam 20, which latter may be of any suitable type as for instance an interfolded or lap joint seam, although preferably of the bead seam type as clearly shown in Figs. 2- and 3, in order that the cap may upon complete removal of this extension band remain as of the usual construction for application or reapplication to the'bottle in the regular way.

The ends of the band 19 are joined in anysuitable manner, as for instance, by an interfolded seam as seen at 21 in Fig. 5 in particular, one extremity projecting in the form of a tongue 22 to provide for ready and complete ripping or tearing of the band completely from the cap and from the bottleneck shoulder 12 in breaking the seal in the first instance, or the well known tongue and slot connection may be utilized. lVhen formed of soft material as described, however, the band may, if so desired, be readily cut away from the bottle neck shoulder and from the cap by a knife or other implement and the tongue 22 dispensed with.

It is obvious from the foregoing that in the initial sealing process after the bottle is filled in the first instance, the cap 15 need only be placed upon the mouth of the bottleneck and may be forced to the position shown in Fig. 2 with the indentations 17 in operative engagement with the bottle neck enlargement 11 either by'hand or by the pressure element 18 which also forces the indentations past the enlargement as seen in Fig. 3 in order to compress the sealing disk 14, the fact that the cap and the neck have locking means engageable by rectilinear movement of the cap onto the neck, permitting this operation to be accomplished in either of the manners stated.

inwardly.-

Proceeding in either way mentioned, it is apparent that when the pressure member 18 has compressed the sealing disk 14 and moved the parts to the position shown in Fig. 3, it is simply necessary to flange or roll the inner free edge of the extension band 19 around the lower edge of the bottle neck shoulder 12, as seen at 19 in Fig. 3, to fasten the entire cap insealed position and in such manner that this seal may be readily broken when it is desired to open the bottle and the band 19 disassociated from the cap in its entirety so that the latter may be taken off and reapplied by rectilinear movement with respect to the bottleneck during the gradual consumption of the contents of the bottle in use.

As seen in Figs. 6 and 7 the indentations 17 of the cap 11 may be more nearly circular and the lower portion of the cap 4' may have an outwardly offset flange 11 for engagement by an upper inner flange of the band 19' instead of the seam 20 before described.

It is obvious, therefore, that my present improvements simplify the construction of both the bottle neck and cap in addition to the operations necessary for their associationwith and disassociation from one another as compared to the construction described and claimed in my patent above referred to.

.I claim 1. The combination with a bottle neck having an annular rounded enlargement and an annular shoulder below the enlargement, of a cap containing aninner sealing member for engagei'nent with the bottle mouth and provided with an annular series of indentations engageable with the annular enlargement of the bottle neck and movable past the same by rectilinear movement of the cap with respect to the bottle neck when pressure is applied to the cap for compressing the said sealing member and a sealing band connected to and carried by the lower edge of the cap and projecting beyond the bottle neck shoulder when the sealing member is compressed and bendable into engagement with said shoulder to hold the cap in sealed position.

2. The combination with a bottle neck having an annular rounded enlargement and an annular shoulder below the enlargement, of a cap containing an inner sealin member for engagement with the bottle mouth and provided with an annular series of indentations engageable with the annular enlargement of the bottle neck and movable past the same by rectilinear movement of the cap with respect to the bottle neck when pressure is applied to the cap for compressing the said sealing member and a sealing band connected to and carried by the lower edge of the cap and projecting beyond the Ill bottle neck shoulder when the sealing memher is compressed and bendable into engagement with said shoulder to hold the cap in sealed position,' said sealing band having a detachable connection with the cap and removable from the latter to permit of subsequent cooperation of the cap and bottle neck through the indentations and enlargement thereof respectively.

- 3. The combination with a bottle neck, of a cap havin an internal sealing member engageable with the mouth of the bottle when pressure is applied to the cap to compress the sai'dsealing member, said cap and said bottle neck being provided with relatively engaging means when the cap is so compressed to hold the cap in sealed position and said cap and bottle neck having relatively engaging means adapted to hold the cap locked upon the bottle neck independent of the sealing means and shiftable into and past their enga ed position in the same direction as require to bring the sealing means into operative relation.-
